We have to follow few steps to integrate twilio with laravel 4.x.

Step 1:

First we have to install package. For this we will add below code on composer.json.

"require": {
    "dtisgodsson/twilio": "dev-master"
}

Step 2:

Then we will update our composer by running below command.

composer update

Step 3:

After installing the package we hava to add provider in app/config/app.php.For this we will use below code.

'Dtisgodsson\Twilio\TwilioServiceProvider'

Step 4:

Now we will publish that package by using command

php artisan config:publish dtisgodsson/twilio

Step 5:

Now create account on twilio and use sid and authToken and default number on below place.

app/config/packages/dtisgodsson/twilio

by this way we can implement twilio using laravel 4.x
